Input 3 values including at least one non angular one.
( d is the angle opposite to side A; e opposite to B; f opposite to C
Click button [ Calculate ] or [ Enter ] key to get all other values and a drawing of that triangle.
Or click in the white left zone to directly draw a triangle.

[ Miror ] to reverse the triangle left to right.
[ Reset] or [ Esc ] key to erase all values.
[ Data ] , or key Q leave only input data. ( Note the two blanks preceding calculated values. )
[ Complementary ] give a second possible solution.
[ degree ] ou [ radiant ] to change angular unit.
[ < ] ou [ > ] ( at top with Triangulator # ) to go backward or forward to preceding solutions.
[ + ] ou [ - ] change the number of decimals to edit.
A value smaller than this precision makes the calculation impossible. Augmenting the precision may be needed.
The last calculation is memorised in a "cookie" and will be installed when this page is reloaded.
